Therefore, a trial run was conducted for the pneumatic flow assistance system, "AirSweep System," designed to provide on-demand bulk material flow. As a result, the product eliminated all blockages near the container outlet, reduced the filling time of bulk bags from 1 hour to 2 minutes, and improved productivity by 3000%. *For more details, please refer to the PDF document or feel free to contact us.

• Emulsifier/Disperser

To manufacture products of superior quality, international major paint and coating manufacturers needed to use a new grade of titanium dioxide (TiO2). The new material consists of finer and lighter particles, which tend to form bridges over the vibration feeder system already installed in the storage silos. Therefore, the feeder was replaced with a live bin bottom, and four "VA-12 (1-1/2") AirSweep units" were installed approximately 60 cm above the live bottom. By solving process issues using this system, we are producing high-quality products while achieving a production capacity greater than expected. *For more details, please refer to the PDF document or feel free to contact us.*

• Emulsifier/Disperser

A major coal-fired power plant in the Midwest of the United States needed to meet federal emissions standards while maximizing power output. To achieve this, the plant installed a Dry Sorbent Injection (DSI) system designed to reduce emissions of hydrochloric acid and sulfur dioxide. However, DSI technology relies on poorly flowing bulk solid materials such as hydrated lime, trona, soda ash, and sodium bicarbonate. Therefore, a "VA-51 AirSweep" was installed in the trough of the screw conveyor. As a result, the power plant has been continuously operational since the fall of 2015, with no compliance issues, thanks to the support of the DSI system and the Airsweep material activation system. *For more details, please refer to the PDF document or feel free to contact us.*

This is a poppet-type solenoid valve with high durability and high responsiveness. By rapidly turning the poppet solenoid valve ON/OFF, it is possible to intermittently blow air (cooling) and significantly reduce the amount of compressed air used. By accurately controlling the frequency (the number of ON/OFF cycles per second) and the duty cycle (the ratio of ON to OFF), it is possible to maintain sufficient blowing force required for the application while reducing compressed air usage by more than 50%. Additionally, our poppet valves are not disposable. We sell internal component sets such as O-rings and pistons, so by replacing worn parts, you can continue to use the main unit. The size of the pulse blow valve is wide-ranging, with options available up to super large diameter (65A)!

• Pneumatic Equipment

Many manufacturers store and retrieve various substances in containers such as hoppers, but due to the shape of the hopper and the nature of the substances, a clogging issue known as bridging occurs near the outlet. Currently, equipment such as air knockers and air vibrators are used to strike or shake the hopper, but while the noise is loud, the effectiveness is limited, resulting in workers having to regularly (or when a clog occurs) go to the site and hit the hopper with hammers or sticks. The completely new proposal that uses compressed air to fully resolve issues like bridging and rat-holing is AirSweep. Examples of resolved substances: aluminum, coal, copper, diatomaceous earth, gypsum, iron ore, limestone, magnetite, phosphates, shale, soda ash, activated carbon, adipic acid, aluminum chloride, boric acid, chlorine, herbicides, hydrated lime, iron oxide, polyacrylamide, titanium dioxide, zinc, animal feed, brewing grains, cocoa, coffee, corn, wheat, hops, salt, edamame, spices, sugar, starch, acetate, cement, chalk, cork, detergents, fertilizers, fly ash, pharmaceuticals, plastics, polymer resins, wax flakes, wood chips, etc.

• Other safety equipment

Content of the scene A valve with a monitoring device performs 1) fault detection, 2) output of fault signals, and 3) prevention of restart when a failure occurs on one side. In particular, 3) ensures that the valve does not operate even if power is supplied during a fault, thereby ensuring the safety of the operator. With monitoring, the operator is freed from checking for air leaks and can focus on more productive tasks.

• Other safety equipment

Scene content As usual, the press operation was underway, but one side of the valve had already malfunctioned. The operator continued to operate without noticing the signs of one-sided failure (air leakage from the exhaust port)... When the power to the valve was turned OFF, both valve bodies failed, resulting in none of the valves closing, which meant that secondary air could not be exhausted, and the press would not stop. The operator could face a "pinching accident."

• Other safety equipment

Scene content: Inside the double valve, two valve bodies repeatedly open and close almost simultaneously. When one side does not close (failure) after the valve is turned off, the valve body on the functioning side closes, and the secondary side air is exhausted, causing the press to stop. However, the double valve can still operate if power is restored even when one side is malfunctioning. Air leakage occurs from the valve's exhaust port, but this "failure indication" is difficult to notice.

• Other safety equipment

Content of the scene: A solenoid valve (power control element) was installed to ensure safety through a redundant structure and cross-checking (mutual monitoring) in a dual-channel system. Therefore, even in a situation where one valve body was broken and could not shut off the hydraulic pressure, the other valve body operated normally, shutting off the hydraulic pressure and returning it to the tank, allowing the operator to safely complete the mold change.

• Other safety equipment

Content of the scene After conducting a risk assessment of the machinery, the failure of the power control element (cylinder control valve) was determined to be a significant risk. It is necessary to introduce products that meet the high safety requirements corresponding to the category/performance level. The introduced valve is a highly reliable, dual-channel redundant valve that ensures power (hydraulic) is reliably cut off even if the hydraulic cylinder control valve fails. In conjunction with the interlock, it cuts off the supply pressure and returns the power (hydraulic) of the moving mold to the tank, allowing the operator to safely perform mold changes.

• Other safety equipment

Scene content: While the machine operator opened the interlocked door to change the mold and was cleaning the mold, the moving mold, which was supposed to stop due to the interlock mechanism, slowly and quietly moved towards him without him noticing. By the time the machine operator realized this... as a result, he suffered severe injuries, having a part of his body caught and severed by the mold.

• Other safety equipment

Scene content The cylinder control valve has been changed to a "double valve." At this time, if the return position of the cylinder is set to the "upper end," even if one side of the double valve fails, the functioning side of the valve body will operate to return the cylinder to the set position. By doubling the pneumatic energy control (double valve configuration) and using an optical safety device, we can avoid accidents involving workers being caught.

• Other safety equipment

Scene content: The operator was unable to set the workpiece properly due to carelessness. There is an optical safety device, so even if the neighboring operator adjusts the workpiece by hand, the machine should stop... The 'valve' controls the rise and fall of the pneumatic cylinder. If the valve fails, even if the safety device operates, the air cannot be switched, and the cylinder will not stop.

• Other safety equipment

Scene content: A machine maintenance technician performing regular machine maintenance during the Golden Week. Following company rules, they search for the residual pressure relief valve to shut off all power energy to the machine, cut off the supply air, and begin venting the residual pressure air in the piping. With a typical ball valve, it takes much longer than expected to vent all the residual pressure air in the piping. If one approaches the machine with the mindset of "Well, as long as it's mostly vented, it's okay," the compressed air that is still present may suddenly cause the cylinder to move.

• Other safety equipment

Scene content: A malfunction has occurred in the manufacturing of a certain product. It is necessary to immediately check the condition of the machinery, and to do so, all power energy that operates the machinery must be shut off. I received instructions to respond urgently. Shortly after joining the company, I learned which one is the shut-off exhaust valve during training, but I don’t remember... The general three-way valve and the shut-off exhaust valve look similar; which one should I shut off?
